Fossil Fuels - Did You Know


  • Natural gas and oil are believed to have been formed millions of years ago when plant and tiny sea animals were buried by sand and rock. Additional layers built up and pressure and heat from the earth changed this material into petroleum and natural gas.
  • Natural gas was first used in the United States in 1816 when gaslights were used on the streets of Baltimore, Md. The first large-scale demand for oil occurred as a result of the kerosene lamp, invented in 1854. (Source: Chevron Learning Center)
  • Natural gas is lighter than air, and is colorless and odorless. Crude oil is typically straw-colored liquid or tar-black solid; however, red, green and brown hues are not uncommon. (Source: Chevron Learning Center)
  • Almost all of the natural gas consumed in the United States is produced in the United States (84 percent).
  • Most of NextEra Energy Resources' natural gas plants use state-of-the-art technology known as a combined-cycle generator, which is about 30 percent more efficient than traditional combustion.
